Reverse lights and signal lights nonfunctional on my 1992 t-bird

The reverse lights and turn signals (inside indicators and outside) are not working on my 92 thunderbird. I've checked the flashers and the fuses, I've replaced the turn signal and hazard light relay, I've replaced the turn signal switch, and I know all the bulbs are good, but still these lights are not working. If anyone has any idea please help me out, I'm completely stumped and so is every mechanic I've been too. I've gotten several different diagnoses on this problem and no solution yet.

Your backup lights and turn signals are on two separate circuits. The backup light work on a switch from your brake pedal. Use a tester to see if you have contact through your switch. If you do, I would that you may have burned out bulbs. Check out this and get back to me.
